OMNUC G5-series (Pulse-train Input Type) AC Servomotors and Servo Drives User's Manual
The DC voltage in the control power supply dropped below the specified value.
The DC voltage in the main circuit power supply exceeded the specified value.
The DC voltage in the main circuit power supply dropped below the specified
value.
Overcurrent flowed through the IGBT. The Servomotor power cable is ground-
faulted or short-circuited.
The temperature of the Servo Drive radiator exceeded the specified value.
Operation was performed with a significantly overrated torque for a few seconds
to several tens of seconds.
The regenerative energy exceeded the regeneration absorption capacity of the
Regeneration Resistor.
The encoder cable was disconnected.
The Servo Drive cannot establish communications with the encoder.
The number of accumulated pulses in the error counter exceeded the value set in
Error Counter Overflow Level (Pn014).
The Servomotor rotation speed exceeded the maximum allowable speed.
The settings of the Electronic Gear Ratio (Pn009 to Pn010, Pn500 to Pn503) are
not appropriate.
The error counter value obtained with reference to the encoder pulses exceeded
29
2 (536,870,912).
An error was detected in the interface I/O signal.
The Servomotor exceeded the allowable operating range set in Overrun Limit
Setting (Pn514) with respect to the position command input.
Data in the Parameter Save Area was corrupted when the power supply was
turned ON and data was read from the EEPROM.
The checksum did not match when the power supply was turned ON and data
was read from the EEPROM.
Both the Forward Drive Prohibition Input and Reverse Drive Prohibition Input
signals turned OFF.
A missed phase-Z pulse was detected.
A logic error was detected in the CS signal.
The combination of the Servomotor with the Servo Drive is not appropriate.
The encoder is not connected when the power supply is turned ON.
